Medical device manufacturing demands precision, reliable materials, and clear traceability. Whether you’re building diagnostic equipment, surgical instruments, or functional prototypes, the manufacturing process needs to deliver repeatable quality without slowing development down.
CNC machining is a strong fit for medical applications because it combines tight tolerances, production-grade materials, and flexibility from prototype to low-volume production.
At Shapeways, CNC machining is available in stainless steel, aluminum, and POM-C, giving engineering teams several options depending on the application.
Stainless Steel 316L: Built for Demanding Environments
Best for: Surgical instruments, housings, fluid-handling components, laboratory equipment, and precision mechanical parts.
316L stainless steel offers excellent corrosion resistance and performs well in environments exposed to cleaning chemicals and sterilization processes.
CNC machining makes it possible to create precise holes, threads, sealing surfaces, and mounting features while maintaining consistent dimensions.
For applications where documentation matters, Shapeways can also provide EN 10204 3.1 material certification for lot-specific material traceability.
POM-C: Lightweight and Low-Friction
Best for: Guides, bushings, moving mechanisms, fixtures, and internal device components.
POM-C is an engineering plastic known for its low friction, dimensional stability, and stiffness.
It machines cleanly, making it particularly suitable for components with moving interfaces or tight mechanical fits.
For parts involving patient contact, suitability should always be assessed against the regulatory and biocompatibility requirements of the specific application.
Aluminum: Lightweight and Versatile
Best for: Diagnostic equipment, medical device frames, housings, robotic systems, fixtures, and prototype assemblies.
Shapeways offers CNC machining in Aluminum 5083, 6082, and 7075.
Aluminum is easy to machine, lightweight, and strong enough for many structural applications. It also allows engineers to integrate pockets, channels, mounting points, and other complex features directly into a part.
Why Use CNC for Medical Device Development?
CNC is especially valuable when teams need to move quickly without investing in tooling.
It works well for:
- Functional prototypes
- Design verification
- Fit and assembly testing
- Pilot production
- Low-volume manufacturing
- Bridge production before tooling
Design changes can be made directly in CAD and manufactured without creating new molds or tooling.
Choosing the Right Manufacturing Process
CNC isn’t the answer for every medical part.
Highly complex internal geometries or patient-specific designs may be better suited to additive manufacturing, while very high-volume plastic parts may eventually make more sense with injection molding.
The right process depends on geometry, material, volume, tolerances, and the stage of product development.
CNC Manufacturing with Shapeways
Shapeways combines CNC machining and industrial additive manufacturing to support medical device companies from early prototypes through low-volume and repeat production.
With CNC materials including Stainless Steel 304 and 316L, Aluminum 5083, 6082 and 7075, and POM-C, engineering teams can select the manufacturing route that best fits their application.
